- physics constant angular acceleration -
**Ajayb**, Wednesday, August 1, 2012 at 1:01am4 rev.= 4*2*pi radians

use the formula for angular motion:

theta = W0*t + (1/2)*alpha*t^2 .....(1)

here theta = 4*2*pi

W0 = 4.3

alpha = 3.75

Solve the quadratic eqn.(1)to get the value of t (time)

The data on radius of the wheel has no use in solving this problem.
